Our aim is to work as efficiently as possible, without making you incur unnecessary costs.

This agreement will include a detailed assignment description, as well as an indication of the expected duration of the investigation. You will also receive a clear overview of our fees and expected costs.
Research
Once the agreement is signed, our private investigators get to work. Depending on the nature of the investigation, we use methods such as observations, shadowing and digital investigation techniques to gather the necessary evidence. In doing so, we respect applicable laws at all times.
Feedback

Final report
At the end of the investigation, you will receive a detailed final report. This report contains a detailed summary of all our findings, including evidence such as photos, videos and written reports. If necessary, this report can be used in court proceedings or negotiations.

This means that your case will be handled with the utmost care and confidentiality.
